LUDGER PROVANUHER, OF DENVER, COLORADO, ASSIGNOR OF ONE-HALF TO THOMASN. BRIEN, OF SAME PLACE.

CARRIAGE-AXLE.

' SPECIFICATION forming part of Letters Patent No. 238,964, dated March15, 1.881.

Application filed October 23, 1880.

To all whom it may concern:

Be it known that I, LUDGER PROVANCHER, ofDenver,in thecounty of Arapahoeand State of Colorado, have invented certain new and useful Improvementsin Axles; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, refer- I0ence beiu g had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to hub-attaching devices for vehicle -axles; andit consists in the construction, arrangement, and combination of parts,as hereinafter more fully described, and specifically pointed outin theclaim.

In the annexed drawings, Figure 1 is aside view of my improved axle withattaching de- 2 vices. Fig. 2 is a longitudinal section of the same.Figs. 3 and 4 are opposite end views of the divided or split nut, andFig. 5 is a view of the oil-cap. A

The outer cylindrical end of the axle A is 2 5 slightly tapered andformed with rings or projecting shoulders a b 0. A suitablepackingriug,'d, of equal diameter with the shoulder b, is placed so asto rest against the inner side of the latter, around the axle, and asimilar packing-ring, e, but of larger size, is also placed around theaxle, on the inner side of the shoulder a, beyond which it projects. Themetallic packing-ring or washer f is placed against the leather orrubber ring 6, and the 3 5 divided nut B having been placed in positionwith its outer end resting against the leather packing-ring d, the twoparts of the divided nut are firmly secured together by means of theflanged ring 0, which is screwed onto 4 their inner ends.

The inner end of the divided nut B is of greater diameter than its outerend, and the nut is formed with screw-threaded necks, that engage withcorresponding threads within the ring (3 and axle-box D. It is alsoprovided with internal shoulders, that correspond with the rings f e andaxle-shoulder a, and with an external flan geor shoulder, B, and flatfaces (No model.)

b 1). The not B and ring 0 having been firmly attached, as abovedescribed, will secure a close fit of the parts and yet allow them tomove freely around the axle.

While the not B is held by a wrenchapplied to the faces I), the hub maybe attached by turning the wheel, and thus screwing the axle-box D intoplace until its inner end rests firmly against the shoulder B.

The axle'box D has an enlarged inner end provided with internalscrew-threads for attachment to the nut B, and at its opposite end isexternally threaded for the attachment of the oil cap or not E. Itsinner surface is shouldered to fit against the axle-shoulders b c, andit is also provided with an oilgroove, g. The axle-box is kept in placewithin the hub, and prevented from turning or working loose by means ofthe feather 01, formed on its outer surface, the cap E and shoulder Balso contributing to the same result.

By means of the cap E at one end, and the close connection of theflanged ring 0 and washers f6 with the not B and axle-shoulder a at theother end, the entrance of sand and escape of oil are elfectuallyprevented.

The hub and axle-box are securely attached to the axle in such a mannerthat they may be readily removed and replaced, when desired, for repairsor other purposes.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination of the axle A, having the shoulders to b 0, divided notB, having flange B and faces b, flanged ring 0, washers d 6f, axle-boxD, having feather d and oilgroove g, and the cap E, all constructed andarranged as and for the purpose specified.

Intestimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
